An adjustable rate mortgage is known as an ARM. An ARM’s interest rate fluctuates over time, in contrast to fixed rate mortgages, which have a constant interest rate for the duration of the loan. Because an ARM’s initial interest rate is lower than a fixed rate mortgage’s, it might be a good choice if you only intend to own your home for a few years, you anticipate future income growth, or the current fixed rate mortgage interest rate is too high.
An index, a margin, an interest rate cap structure, and an initial interest rate period are the four parts of an ARM. The new interest rate is determined by adding a margin to the index after the initial interest rate period has ended. At the time of loan application, your lender will reveal the margin (it’s a good idea to shop around for a low margin, as margins may vary from lender to lender). Your interest rate will change in accordance with changes in the index figure.
The Constant Maturity Treasury (CMT) index, which is the weekly average yield of U.S. Treasury securities adjusted to a constant maturity of one year, or the 1-year London Interbank Offered Rate (LIBOR) are both acceptable index options on FHA insured ARM loan transactions. Your loan’s interest rate cap structure will restrict interest rate increases and decreases.
There is some protection against significant fluctuations in interest rates thanks to the interest rate cap structure. There are two kinds of caps: life-of-the-loan and annual. While the life-of-the-loan cap restricts the maximum (and minimum) interest rate you can pay for the duration of your mortgage, the annual cap limits the amount your interest rate can change, either up or down, in any given year. FHA provides four “hybrid” ARM products in addition to a standard 1-year ARM. For the first three, five, seven, or ten years, the initial interest rate offered by hybrid adjustable rate mortgages (ARMs) remains fixed. The interest rate will change once a year after the initial period. The various interest rate cap structures for the different ARM products are listed below:
After the first fixed interest rate period, 1- and 3-year ARMs may increase by one percentage point per year, and over the course of the mortgage, they may increase by five percentage points.
5-year adjustable rate mortgages (ARMs) can be increased by either one percentage point per year and five percentage points over the mortgage’s life, or by two percentage points per year and six points over the mortgage’s life.
Only two percentage points may be added to 7- and 10-year adjustable rates each year following the first fixed interest rate period, and six percentage points may be added over the course of the mortgage.
